Final Project - Storm Events

Project Goals

The occurrence of storms and other significant weather phenomena having sufficient intensity to cause loss of life, injuries, significant property damage, and/or disruption to commerce. Rare, unusual, weather phenomena that generate media attention, such as snow flurries in South Florida or the San Diego coastal area and other significant meteorological events, such as record maximum or minimum temperatures or precipitation that occur in connection with another event.

By analyzing the storms events, we can get some insights into impact of storm events.

NCDC Storm Events Database

The data set used in this analysis is obtained from NCDC Storm Events Database. Storm Data is provided by the National Weather Service (NWS) and contain statistics on personal injuries and damage estimates. Storm Data covers the United States of America. The data began as early as 1950 through to the present, updated monthly with up to a 120 day delay possible. NCDC Storm Event database allows users to find various types of storms recorded by county, or use other selection criteria as desired. The data contain a chronological listing, by state, of hurricanes, tornadoes, thunderstorms, hail, floods, drought conditions, lightning, high winds, snow, temperature extremes and other weather phenomena.

For my analysis, the data set contains only storm events from 2017.
